limit as x approaches-1 of sqrt(x^2-1)

x \to - 1 lim (x^{2} - 1)

0

Solution steps

x \to - 1 lim (x^{2} - 1)

Plug in the value

x = - 1

= (- 1)^{2} - 1

Simplify

(- 1)^{2} - 1 : 0

= 0

f (x) = (3 x + 4) (5 - x^{2}) (4 + x^{2})

x \to \infty lim (e^{x} + 3)

\int_{0}^{\infty} e^{- \frac{x}{4}} d x

x \to 0 lim ((1 + x)^{\frac{2}{x}})
